As the wind speed increasing means B, those having various shapes to be described in detail later are adopted.

  Here, the result of analyzing the improvement plan will be described by taking the 1/4 model of the air-cooled heat pump chiller as an example.

  Improvement plan 1-1: A punching metal 18 having an opening ratio of 20% is installed in the upper first third of the heat exchanger 1A (see FIG. 4).

  Improvement plan 1-2: A punching metal 18 having an opening ratio of 20% is installed in the upper half of the upstream side of the heat exchanger 1A (see FIG. 5).

  Improvement plan 1-3: A punching metal 18 having an opening ratio of 20% is provided on the entire upstream surface of the heat exchanger 1A (see FIG. 6).

  The results of the analysis in the improvement plans 1-1, 1-2, and 1-3 were as follows. 7 to 9, solid lines 1 to 3 indicate the characteristics of the heat exchangers 1A to 1C, and dotted lines 1 to 3 indicate conventional heat exchangers 1A to 1A (that is, the case where the wind speed reducing means A is not provided). The characteristics of 1C are shown.

  In the case of the improvement plan 1-1, as shown in FIG. 7, the wind speed in the upper part of the heat exchanger 1A is reduced. Moreover, when the flow rate of air passing through the heat exchanger 1A is reduced, the flow rate of air passing through the heat exchanger 1B is increased, and the uneven distribution degree of the passing wind speed distribution between the heat exchangers 1A to 1C is reduced. In addition, the upper and lower wind speed distributions in the heat exchangers 1 </ b> A to 1 </ b> C are all wind speed distributions having an inflection point near the lower end of the punching metal 18.

  In the case of the improvement plan 1-2, as shown in FIG. 8, the uneven distribution degree of the passing wind speed distribution between the heat exchangers 1A to 1C is further improved. Moreover, the drift between the upper and lower sides of the heat exchangers 1A to 1C is improved.

  In the case of the improvement plan 1-3, as shown in FIG. 9, the passing wind speed distribution between the heat exchangers 1A to 1C is substantially uniform. Moreover, the drift between the upper and lower sides of the heat exchangers 1A to 1C is improved.

  Improvement plan 2-1: A plate-shaped baffle plate 20 acting as a plate-shaped wind speed increasing means B is installed below the heat exchangers 1A and 1B (see FIG. 10).

  Improvement plan 2-2: An L-shaped plate 21 having a horizontal portion 21a and a vertical portion 21b acting as the wind speed increasing means B is installed below the heat exchangers 1A and 1B (see FIG. 11).

  Improvement plan 2-3: An inverted L-shaped receiving plate 22 having a horizontal portion 22a and a vertical portion 22b acting as wind speed increasing means B is installed below the heat exchangers 1A and 1B (see FIG. 12). .

  Improvement plan 2-4: Reverse L having horizontal portion 22a and vertical portion 22b acting as wind speed increasing means B at the lower part of heat exchangers 1A and 1B, and securing clearance S with heat exchanger 1B A letter-shaped greeting board 22 is installed (see FIG. 13).

It is installed (see Fig. 14).

  The results of the analysis in the above improvement plan 2-1 to improvement plan 2-5 were as follows. 15 to 19, solid lines 1 to 3 indicate the characteristics of the heat exchangers 1A to 1C, and dotted lines 1 to 3 indicate conventional heat exchangers 1A to 1A (that is, when the wind speed increasing means B is not provided). The characteristics of 1C are shown.

  In the case of the improvement plan 2-1, as shown in FIG. 15, by installing the baffle plate 20 below the heat exchangers 1A and 1B, the effect of suppressing local peeling at the lower part of the heat exchanger 1B can be confirmed. .

  In the case of the improvement plan 2-2, as shown in FIG. 16, as in the case of the improvement plan 2-1, the local separation at the lower part of the heat exchanger 1B is performed by changing the inflow angle to the lower region of the heat exchanger 1B. The effect which suppresses can be expected.

  In the case of the improvement plan 2-3, as shown in FIG. 17, the passing wind speed in the lower region of the heat exchanger 1B is improved.

  In the case of the improvement plan 2-4, as shown in FIG. 18, the passing wind speed in the lower region of the heat exchanger 1B is improved.

  In the case of the improvement plan 2-5, as shown in FIG. 19, in order to improve the passing air speed distribution in the lower region of the heat exchanger 1B, the passing air speed increases in the lower part of the heat exchanger 1B + to the lower part of the heat exchanger 1B. For the purpose of changing the inflow angle of the heat sink in the direction perpendicular to the heat exchanger 1B, the shape of the attacking plate 22 is bent and bent in multiple stages from the introduction side to the outlet side, and peeling on the outside of the attacking plate 22 occurs. Is suppressed, and the passing wind speed distribution in the lower region of the heat exchanger 1B is improved.

  From the above results, it can be said that the improvement plan 2-5 that can improve the passing wind speed distribution in the lower region of the heat exchanger 1B is most desirable.

The results of the analysis in the improvement plan 3-1 to the improvement plan 3-3 were as follows. 20 to 22, solid lines 1 to 3 indicate the characteristics of the heat exchangers 1A to 1C, and dotted lines 1 to 3 are the conventional ones (that is, when the wind speed reducing means A and the wind speed increasing means B are not provided). The characteristic of heat exchanger 1A-1C is shown.

  In the case of the improvement plan 3-1, as shown in FIG. 20, by installing the punching metal 18 on the entire surface of the heat exchanger 1A, the passing wind speed distribution between the heat exchangers 1A to 1C is almost uniform, and the heat exchange The drift between the top and bottom is also improved. Moreover, since the receiving plate 22 (refer FIG. 14) is installed in the lower part of the heat exchanger 1B, the local fall of the wind speed in the lower area | region of the heat exchanger 1B is also improved.

  In the case of the improvement plan 3-2, as shown in FIG. 21, since the upper portion of the heat exchanger 1A is open, the passing wind speed distribution in this region is not improved. However, since most of the suction area of the heat exchanger 1A is closed by the electrical component box 17, the drift between the heat exchangers 1A to 1C is improved. Moreover, since the receiving plate 22 (refer FIG. 14) is installed in the lower part of the heat exchanger 1B, the local fall of the wind speed in the lower area | region of the heat exchanger 1B is also improved.

  In the case of the improvement plan 3-3, as shown in FIG. 22, by passing the punching metal 18 in the area where the upper part of the heat exchanger 1A is open, the passing wind speed in the upper area of the heat exchanger 1A is suppressed. Therefore, the drift in the height direction of the heat exchanger 1A is improved, and the passing wind speed distribution between the heat exchangers 1A to 1C is substantially uniformized. Moreover, since the receiving plate 22 (refer FIG. 14) is installed in the lower part of the heat exchanger 1B, the local fall of the wind speed in the lower area | region of the heat exchanger 1B is also improved.
